If you're using the ASP.NET membership you're probably aware that one of the things it usesto keep the user logged in can be a cookie. This cookie can be used to store additional details also to help you cut down on the database calls required for simple things like the user's name or email address.

I had an issue this weekend while updating some code from WebForms to MVC3 when using the brilliant CKEditor. Many of our forms display 2 submit buttons - one for publishing and one to save as a draft. When using WebForms there was never any issue with this. I'd just make 2 <asp:Buttons>, add some On_Click handlers and everything was great. With MVC3 I noticed that when using the CKEditor on my forms that I was having to click on the submit buttons twice before the page would submit.
